Now the dom0 shows a lot of 4gb seg fixup messages in console, but that's another question, and I think I can fix it as I've seen about that before.

It does not look right. It's best to limit dom0 memory from the get-go.

Is it safe to assume that as soon as the driver has loaded, it will no longer need to call xen_create_contiguous_region anymore and we can use up all free Xen memory If so, it requires nonzero Xen free memory ?

It sounds like a driver issue to me, even though you wouldn't think so since the hardware and drivers are standard with VMware. #8 Nothinman, Jul 12, 2012 dalearyous Senior And you certainly realize that there are other things some drivers do that don't work under Xen without modification - these cases also only get handled as people run into them.

The more memory is free the greater the chance that a sufficient chunk exists. The driver requests DMA memory and the request fails. If you'd like to contribute content, let us know.

It is strange that it uses same pci-id as some different driver.

From a terminal window please run: apport-collect 667478 and then change the status of the bug back to 'New'. I guess the error message from ifconfig could be improved? Increasing the memory for the domain does not seem to help, unless one assigns a significant fraction of all system RAM.
